clk: tegra: Support unique names for multi-socket platforms

Browse Source 
On multi-socket platforms each socket has its own BPMP which exposes the
same clock names. Fix this by using the NUMA ID as a prefix for the
clock names on multi-socket platforms.

Use 'sizeof(info->name)' in the strscpy() and snprintf() functions to
future proof against anyone changing the size of the 'name' array.
